how much torque can a stock evo 9 clutch handle before slipping?

 

if you do not launch it will live with 400 lbft on the fly

 

Awesome!! Sounds like I should be good for a while then right now I'm at 313 awhp and 321 lb ft awtq, but I eventually want to be closer to 400

 

320 to 340 for a short life span. I seen it up to 390, but I wouldn't chance it.

 

also depends on the miles on the stock clutch. New OEM clutch will hold more than used 100K miles clutch.

 

exactly..

also, if you remove the rubber restrictor in the clutch line, it will last longer..

 

My clutch is about 12k miles on it so I should be okay for a while

 

Hey, if it slips it slips, then I'll upgrade it , I can do the work myself so I'm not worried about it haha

 

My stock clutch only lasted 20 or 30k miles and all i did was an electronic boost controller. I did some launches for sure but I wasnt a regular street racer or anything. I wouldnt worry about it unless the car is allready apart. Just use it till it goes and then put in an ACT clutch (I was very happy with mine, almost like stock but can handle 500ftlbs or so). If its allready apart, then absolutely put in an ACT, its only a few hundred.

 

Stock clutch won't last at 400 ft-lbs if you use 2-step launch control. I got less than 10 launches and my clutch was gone. Start saving up for a new clutch once you hit 400ft-lbs. If you need time, avoid launching. You will know every time your clutch is getting hurt, by sniffing the air for burnt clutch.

 

organic clutches dont like launches, period.
